M249 MK1 Owners - Need a favour

[Austeyr]

I’m looking for somebody with an AEG M249 Mk1 (Like in the image) that can send me a few photos

I need:
A clear photo of how the carry handle is attached to the barrel
How far the rear sight is from the back flat part of the lid
The gas block regulator plug and how it attach

Any and all help greatly appreciated
